Abstract
The presently described technology provides a method for adaptive image processing. The image processing method includes determining an entrance exposure of an object, determining an exit exposure of the object, and determining one or more image processing parameters based at least in part on the entrance and exit exposures. The presently described technology also provides a method for adaptive image display. The image display method includes determining an entrance exposure of an object, determining an exit exposure of the object, and displaying an attenuation map based at least in part on the entrance and exit exposures.
Claims23
A method for image processing comprising:
- using an imaging system to acquire a raw image of an object by passing energy through the object;
- determining an entrance exposure of the imaged object, wherein the entrance exposure comprises an amount of energy that entered the imaged object when the raw image was acquired;
- determining an exit exposure of the imaged object, wherein the exit exposure comprises an amount of energy that exited the imaged object when the raw image was acquired;
- using an image processor to calculate a ratio of the exit exposure to the entrance exposure;
- using a data source operably connected to the image processor to correlate the ratio of the exit exposure to the entrance exposure with one or more image processing parameters that can be used to enhance the acquired raw image of the object;
- and
- at least one of:
- adjusting one or more existing image processing parameters based on the correlated one or more image processing parameters,
- not adjusting one or more existing image processing parameters that are about equal to the correlated one or more image processing parameters, and
- selecting the correlated one or more image processing parameters that are new.
A non-transitory computer-readable storage medium encoded with a set of instructions for a computer, said set of instructions including:
- a first routine configured to acquire a raw image of an object, the raw image being acquired by passing energy through the object;
- a second routine configured to determine an entrance dose of the imaged object, wherein the entrance dose comprises an amount of energy that entered the imaged object when the raw image was acquired;
- a third routine configured to determine an exit dose of the imaged object, wherein the exit dose comprises an amount of energy that exited the imaged object when the raw image was acquired;
- a fourth routine configured to use an image processor to calculate a ratio of the exit dose to the entrance dose;
- a fifth routine configured to correlate the ratio of the exit dose to the entrance dose with one or more image processing parameters that can be used to enhance the acquired raw image of the object;
- and
- a sixth routine configured to at least one of:
- adjust one or more existing image processing parameters based on the correlated one or more image processing parameters,
- not adjust one or more existing image processing parameters that are about equal to the correlated one or more image processing parameters, and
- select the correlated one or more image processing parameters that are new.
A system for image processing comprising:
- an imaging system configured to acquire a raw image of an object by passing energy through the object;
- and
- an image processor configured to receive an entrance exposure comprising an amount of energy that entered the imaged object when the raw image was acquired,
- the image processor configured to receive an exit exposure comprising an amount of energy that exited the imaged object when the raw image was acquired,
- the image processor configured to calculate a ratio of the exit exposure to the entrance exposure,
- the image processor being operably connected to a data source configured to allow the ratio of the exit exposure to the entrance exposure to be correlated with one or more image processing parameters that can be used to enhance the acquired raw image of the object, and
- the image processor configured to at least one of:
- adjust one or more existing image processing parameters based on the correlated one or more image processing parameters,
- not adjust one or more existing image processing parameters that are about equal to the correlated one or more image processing parameters, and
- select the correlated one or more image processing parameters that are new.
